Outline of Final Research Achievements |
We generated continuous galectin-3-overexpressed LNCaP cells and galectin-3-downregulated PC-3 cells using siRNA. Overexpression of galectin-3 in LNCaP cells promoted invasion and migration of tumor cells comparing with control LNCaP cells. Downregulation of galectin-3 in PC-3 cells suppressed invasion and migration comparing with control PC-3 cells. Galectin-3 significantly suppressed anti-androgen effect induced by enzalutamide or bicalutamide in LNCaP comparing with controls by activating androgen transcriptional activity of AR. Galectin-3 has been shown to promote activation of osteoclasts because TRAP-positive cells of the osteoclast was significantly increased 1.7-fold by the addition of recombinant galectin-3. These data indicate that galectin-3 is involved in the tumor progression and anti-androgen drug resistance of CRPC by regulating invasion, migration, transcriptional activity of AR, and osteoclast activity.
